DICTIONARY OF INDIAN TRIBES OF THE AMERICAS - Second Edition contains information on over 1,150 tribal nations of the entire western hemisphere, from the Aleuts of the Arctic region to Onas in southern Argentina and Chile.  This is a contemporary work and its intention is to bring modern day insights to the consideration of the native peoples who populate the western hemisphere.  Every effort has been made to include tribes that have not been extensively covered in other publications.  Modern anthropologists and historians tend to agree that there is a basic homogeneity (cultural, social, biological, or other similarities within a group) among the native peoples of the Americas that need to be considered when any of the tribes are studied. The tribal entries were written by noted local, national and international historians and anthropologists.
